Height of a Projected Object If air resistance is Why or why not? neglected, an object projected straight upward with an initial velocity of 40 meters per second from a height of 50 meters will be at a height s meters after t seconds, where
(a) What are the restrictions on t?
(b) Graph the function s in a suitable window.
(c) Use the graph to find the time at which the object reaches its highest point.
(d) Use the graph to find the maximum height reached by the object.
(e) Write the equation that allows you to find the time at which the object reaches the ground. Then, solve the equation, using the method of your choice. Give your answer to the nearest hundredth of a second.
